Against Method

Against Method: Outline of an Anarchistic Theory of Knowledge is a 1975 book by Austrian philosopher of science Paul Feyerabend. The central thesis of the book is that science should become an anarchic enterprise.[1] In the context of the work, the term "anarchy" refers to epistemological anarchy, which does not remain within one single prescriptive scientific method on the grounds that any such method would restrict scientific progress. The work is notable in the history and philosophy of science partially due to its detailed case study of Galileo's hypothesis that the earth rotates on its axis and has since become a staple reading in introduction to philosophy of science courses at undergraduate and graduate levels.[2] Against Method contains many verbatim excerpts from Feyerabend's earlier papers including "Explanation, Reduction, and Empiricism", "How to be a Good Empiricist: A Plea for Tolerance in Matters Epistemological", and "Problems of Empiricism, Part I." Because of this, Feyerabend claims that "[Against Method] is not a book, it is a collage."[3] Later editions of Against Method included passages from Science in a Free Society. https://en.wikipedia.org/wiki/Against_Method

Paul Feyerabend states his purpose at the outset, which is to convince the reader that all methodologies are limited and that we should support the pluralism of theories and metaphysical views... Since it was first published in 1975, Against Method has followed Karl Popper's The Logic of Scientific Discovery and Thomas Kuhn's The Structure Of Scientific Revolutions into becoming a classic text in the debate about scientific methodology and scientific reasoning.
